TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Dec. 26,1905.

Original application filed October 16, 1902, Serial No. 127,540. Divided and this application filed J 11119 13,1903. Serial No. 161,262.

To all whom it may concern:

Be it known that I, ALEXANDER T. BROWN, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to type-writing machines; and, generally speaking, the object of the invention is to provide means for enabling the machine as a whole to be readily tilted to afford access to the bottom of the machine without liability of interfering with or injuring the parts.

To the above and other ends, which will hereinafter appear, my invention consists in the features of construction, arrangements of parts, and combinations of devices hereinafter described, and particularly pointed out In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a perspective view of a sufficient number of parts of one form of type-writing machine to illustrate my invention in its embodiment therein. Fig. 2 is a central vertical fr0nttorear sectional view of the same.

The present case is a division of my application, Serial No. 127,540, filed October, 16, 1902.

The frame of the machine comprises side plates 1, which are provided with inwardlyprojecting lugs 2, to which the type-bar segment 3 is connected by means of screws 4 in order to support the segment in place and unite the side plates. These side plates are further connected by a type-bar support 5, which is secured at its ends by screws 6 to the side plates and by guide-plates 7 for the finger-keys. (Not shown.) The type-bar segment 3 is slotted for the reception of typebar hangers 8, to which the type-bars 9 are pivoted at 10. It should be understood that each type-bar is connected at 11 to suitable key-controlled devices in order to actuate the typeb ars, it being unnecessary, however, for the purpose of my present invention to illustrate these controlling devices and keys. The side plates 1 are provided with rockers 12, that are preferablyformed integral therewith and extend upwardly and rearwardly from the base of the machine and are united at their upper ends by oppositely-grooved tracks 13, set in an inclined plane and constituting further connections between the side plates or the rockers thereof. These grooved rails are adapted to receive antifriction-balls 14, that are likewise received in the gooves 15 of the carriage 16, in which a platen 17 is mounted to rotate. It will be observed that the rear edges of the rocker-arms 12 are curved upwardly and rearwardly at 18 from the base of the machine to the rear portion thereof, where each terminates in a flattened portion 19. By these means the machine may be tilted back on the rockers without lifting the machine bodily when it is desired to gain access to the working parts from the bottom of the machine, and the weight of the machine is so disposed that when it is turned back on the rocker-arms and rests on the rear portions thereof the machine will be substantially balanced and will stand on end, and there is no liability of it accidentally rocking back or dropping from this position, and it cannot turn over rearwardly, because it will be positively arrested by the upper portions 20 of the arms of the rocker, which constitute stops therefor. Furthermore, it will be seen that there are -no working parts of the machine which extend rearwardly of the rear edges 18, 19, and 20 of the rocker or rockerarms, so that there is no interference by the working parts to the free rocking movement of the machine on its rocker or rocker-arms, and there is no opportunity for any of the working parts to become deranged or broken when the machine is turned back, the carriage and all the parts which connect therewith extending forwardly of the rear faces of the rocker-arms.

. It will be understood that two portions 12 may be said to constitute a rocker or rockerbase, forming, as they do, portions of the base constituted by the lower portions of the side plates, and that the rocker or rocker member enables the machine to be rocked up and supported on end in an upturned position.

In the particular structure shown the rocker-arms perform a twofold function that of supporting the carriage and the parts connected thereto forward of the rear faces of said rocker-arms, and they constitute a rocker or rockers upon which the machine may be tilted to inspect the bottom thereof or gain access to the working parts from the bottom of the machine. 1

While I have shown the features of my invention applied to a front-strike type-writing machine, it should be understood that from ICC What I describe as my invention, and desire to secure by Letters Patent, is

1. A type-writing machine having a rocker on which the machine may be tilted and wholly supported in the tilted position.

2. A type-writing machine having a rear wardly-disposed rocker on which the machine may be tilted or turned back to gain access to the bottom thereof, and on which the machine may be wholly supported in the tilted position.

3. A type-writing machine having a rocker at the rear portion thereof which enables the machine to be tilted rearwardly and maintained on end without resting on the carriage. v

4. In a type-writing machine, the combination of a machine-frame having rocker arms, and a carriage that is carried forward of the rear faces of said rocker-arms and is protected thereby when the machine is turned on end on said rocker-arms.

5. A type-Writing machine having a rocker that is curved upwardly and rearwardly from the base of the machine to the rear portion thereof and having a flattened portion that extends upwardly from the termination of the curved portion of the rocker, and on which the machine is adapted to rest when tilted.

6. A type-writing machine having a rocker on which the machine is adapted to be tilted, said rocker extending beyond all of the working parts of the machine so that the working parts are protected frominjury during the rocking of the machine and when it rests in the tilted position.

7. A type-writing machine having rockerarms that are curved upwardly and rearwardly from the base of the machine to the rear portion thereof and having a flattened portion that extends upwardly from the termination of the curved portion of each rockerarm, and the rear faces of which extend rear- Wardly beyond the working parts of the machine, and onwhich rocker-arms the mac hine is adapted to be tilted.

8. A type-writing machine having a rocker on which the machine may be tilted, the disposition of the rocker and the weight of the machine being such that the machine will be maintained on end when tilted to such position and supported wholly on the rocker.

9. A type-writing machine having rearwardly-disposed rocker-arms on which the machine may be tilted to expose the bottom of the machine, the parts being so constructed and arranged that the machine will be substantially balanced and held in position by the rocker-arms when tilted on end on said rocker-arms.

10. A type-writing machine including side plates that constitute portions of the ma chine-frame, and rockers on said side plates and on which the machine may be rocked or tilted and by which the machine may be wholly supported on end.

11. A type-writing machine including side plates that constitute portions of the machineframe, and rearwardly-directed curved rockers on said side plates and on which the machine may be rocked 0r tilted, said rockers-having flattened portions that extend upwardly from the termination of the curved portion of said rockers.

12. A type-writing machine includingside plates that constitute portions of the machine-frame, and rearwardly-directed rockerarms that are curved to form rocking faces and are flattened at their rear port-ions to provide supports on which the machine may rest with the bottom thereof exposed.

13. A type-writing machine having a main frame so curved and constructed that the machine may be rocked or tilted on the curved portion ot the frame and supported in its tilted position wholly by said frame.

Signed at Syracuse, in the county of Onondaga and State of New York, this 11th day of June, A. D. 1903.
